CONCRETE WALL.

SPECIFICATION forming part of Letters Patent No. 504,194, dated August29, 1893.

Application filedFebruary 6, 1892. Renewed J ly 11, 1893. $erial No.480,175. (No model.)

To 00% whom, it may concern:

Be it known that 1, JOHN W. BEAUMONT, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented new anduseful Improvements in Concrete Walls, of which the following is aspecification.

This invention relates to the construction of concrete Walls, floors andceilings and particularly to that class of studding-walls or partitionsin which the studding is surrounded by concrete blocks keyed to eachother and to the studding in such a manner as to form a strongfire-proof partition wall at comparatively small expense.

The invention consists in the construction of a fire-proof concretestudding-wall as hereinafter described and claimed.

In the annexed drawings-Figure 1 represents in horizontal section aportion of a concrete wall constructed according to my invention. Fig. 2is a vertical transverse section of the same showing how the superposedcourses of concrete blocks may be connected by tongue and groove joints.Fig. 3 is a horizontal section showing how the ends of adjacent blocksmay be provided with tongue and groove joints.

Referring to the drawings, the numeral 1 designates studding posts whichmay be disposed at any suitable or convenient intervals as usual instudding walls or partitions. These studs or posts 1 may be composed ofwood, iron or other metal, or any other appropriate material accordingto the character of the proposed structure. As contemplated by myinvention each stud is provided on one or more sides with a verticallongitudinal groove 2 for reception of a key or keys 3 to assist insecuring in place the concrete blocks 4 that are to complete the wall.

The concrete blocks 4 may be molded from any suitable composition ofmatter such as commonly employed in the preparation of concrete forbuilding purposes. In each block is a recess 5 corresponding with thegroove 2 of the stud l and, like said groove, adapted to receive aportion of one of the keys 3 that assist in securing the block 4 inplace.

In Fig. 1, I have shown separate concrete blocks 4 on the opposite sidesof a stud, the said blocks being approximately L shaped and so arrangedthat when in position their short arms meet at the line 6 on one side ofthe stud. It is obvious, however, that the division line 6 may bedispensed with and each block be molded in such form that it will beadapted to embrace the opposite sides of one or more studs as shown inFig. 3. The long arms of the concrete block or blocks 4 extend beyondthe stud, when in position, as shown. In the inner side of each longarm, at its end, is a dovetail recess 7 which together with thecorresponding recess of the other arm serves to engage a key 8 thatfills the space between the ends of the block or blocks and locks saidends together on one side of the stud.

The wall is built up by laying successive courses of the concrete blocks4 so as to surround the studding, as shown, and as each course is laidthe keys 3 and 8 are inserted in place as required. These keys 3 and 8may have a length equal to the height of one or two blocks 4, aspreferred. In practice I may provide the upper and lower sides of theblocks 4 with tongues 9 and grooves 10 Fig. 2, to interlock withcorresponding parts of adjacent blocks. The ends of the blocks 4 mayalso be provided with tongues ll-andgrooves 12 Fig. 3 for a similarpurpose. These tongues and grooves, however, are not essential. Toeconomize material and lessen the weight of the concrete blocks 4 theymay be molded with vertical openings 13 disposed at suitable points soas not to impair the strength of the wall. These vertical openings 13will be arranged at corresponding points in the superposed blocks so asto form suitable communicating passages for inclosing gas and waterdistributing pipes.

I have shown the keys 3 as being rectangular in form and the keys 8 ashaving wedge shaped or inclined sides, but while these forms of keys arewell adapted to their intended purposes and are such as to permit aready fitting of the keys, it is obvious that the shape of the keys maybe varied to suit the convenience of application.

It will be seen that a concrete wall of the character described in whichthe studding is completely covered with concrete blocks keyed in place,as shown, can be readily constructed without great expense and will bedurable and substantially fire-proof. A wall of this con struction willbe impervious to heat, eoldand dampnQSS; affords n0 lodgmentforiverminor the germs of disease; and posesses the further advantagesof great strength and durability.

What I claim as my invention is- 1. A wall composed of studding,concrete blocks embracing the studding andeach provided with a dovetailrecess 7 which lies opposite the studding to which the block is applied,and a key 8, engaging each dovetail recess and arranged flush with thesurface of the hwbstanfially as describe 2. In a concrete wall, thecombination of studs provided on oppositeisideslwith longitudinalgrooves, concrete blocks surrounding said studs and having recesses intheirrsides and i t e adjac nt-end an i k y Inserted;
